Specification of Letters Patent.

Application filed December 17, 1907. Serial No. 406,914.

7 To all whom it may concern:

Be it known that I, MICHAE HENRY, citizen of the United States, residing at Terre Haute, in the county of Vigo and State of In diana, have invented new and useful Improvements in Scissors-Sharpeners, of which the following is a specification.

My invention pertains to devices for sharpening scissors and other edge tools; and it contemplates the provision of a simple and V inexpensive device through the medium of which scissors may be expeditiously sharpened in a correct manner with but a minimum amount of effort and without entailing the employment of skilled labor. I

The novelty, utility and practical advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a perspective view illustrating the device constituting the best known embodiment of my invention and also illustrating a pair of scissors as properly fastened in the device and positioned to be sharpened. Fig. 2 is a vertical section, on a slightly enlarged scale, illustrative of the arrangement of the rotatable upright of my device in the fixed sleeve by which the same is supported. Fig. 3 is a detail view partly in section and partly in elevation, showing the novel clamp of my improved device. Fig. 4 is a detail plan of the tool-holding clamp.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which: 1 kit is a support which may be a table or the B is the base of my improved sharpening device, and C is a clamp which is illustrated as one means through the medium of which the base may be fixedly secured on a table or other support. While I prefer to have my novel device comprise a base such as ust described, of hardwood or other suitable ma terial, I desire it understood that without in,- volving departure from the scope of my in,-

' vention as claimed, the base may be formed by a table top or may be of any other character compatible with the purpose of my invention.

Fixed-in a recess a of the base B is a stone or other suitable abrasive medium D, and in addition to the base B and the abrasive meupright E fixed to the base at about the distance shown from the abrasive medium, a rotatable upright F having its lower portiondisposed in the said tubular upright E and equipped with a collar 1) which is fixed to it by a set screw 0 or other suitable means,

and is designed to bear and turn on the upper end of the upright E, a guide rod G pivoted atd to the upper portion of the rotatable upright F and arranged to swing vertically, a sleeve H receiving and movable rectilinearly in opposite directions on the guide rod H and having depending clamping members I and a bolt J extending through the same and a wing nut K mounted on said bolt and arranged to crowd the members I toward each other, an arm L, preferably of twisted sheet-metal having its upper vertically disposed portion 0 dis osed between the clamping members I an mounted to swing vertically on the bolt J, a scissors-engaging clamping member M arranged to cooperate with a complementary clamping member formed by the lower portion of the arm L, and a bolt P and wing or other suitable-nut. arranged to cooperate with the said clamping members M and N to fasten a pair of scissors to the sharpening device. I prefer in the manufacture of my improved device to form the clamping members I of a sin le piece of sheetmetal which straddles and 1s curved in conformity to the sleeve H and is brazed thereto.

As clearly illustrated in Figs. 1 and 3, the clamping member N formed by the lower portion of the arm L is provided with an upwardswell or raised portion 6, a forward shoulderf disposed at an acute angle to the longitudinal median line of the arm L, and a lip g reaching forward from the shoulderf and having its forward edge arranged parallel to the said shoulder. It will also be seen by reference to Figs. 1 and 3, that the upper clamping member M has a rear flange h and a forward flange i; the said flange '5 being disposed at an acute angle to the longitudinal median line of the arm L so as to enable its lower edge to bear on the lip g throughout the length thereof.

The scissors to be sharpened are arranged in my novel device in the manner illustrated in Fig. 1that is to say, one blade of the scissors is arranged on the lip g with the rear edge of the blade bearing against the shoulder f of clamping member N, and the dium D my novel device com rises a tubular blade is clamped and securely held --against the said lip g by the forward flange i of'the' upper clamping member M. At thiszpointr it will be noted that by reason of the slioul der f of the clamping member N b(-.iHg'diS' posed at an acute angle to the longitudinal medianline of Q the arm-L, the scissors blade is positioned at an acute ang-le to the linein which the sleeve H is reciprocated or moved w rectilinearly with the result that the said.

blade will be moved over 'the abrasive? medium D while positioned at an acute? 'angle to the'line of movement. 'This con-f -du-ces' to the expeditious aiid proper sharpen 5 ing of the blade, and is advantageous "for;

that reason.

'In=the practical operation of my device;v the scissors are arrangedwith one'blade on the. abrasive medium D and in the clamp on,

' the arm L, and the operatorthenrgrasips the scissors and moves the blade'thereo over the abrasive medium until'the said blade'is: sharpened to the extent desired/ In this connection it will be noticed that during the 5 sharpening-operation, "the pivotal connection (1 enables the operator to' press the blade as necessary against the abrasive medium, while the rotatable upright'F permits of the blade'being'freely moved in the direction of its 'length to and fro over the abrasive r 3 'the' blade.

medium, and the sleeve H movable recti- 'linearly on "the guiderodG perniits oftlie blade being moved toand'fro over the abrasive medium inthe direction of a the width of These several movements of the blade relative to the abrasive medium D tacilitate'the proper sharpening of'the blade with the result that such sharpening is .quickly accomplished and with the 'expendi 40 ture of but 'a minimum amount of effort.

The armL is preferably connected with the reoiprocatory sleeve H in the adjustable 'manner described in order that said arm may beadjusted and adjustably fixed'in order to roperly dispose the "blades of scissors of 'fferent sizesto the stone or abrasive'mediuiii D.

In'a'ddition to the practical advantages hereinbefore ascribed to my, novel scissors sharpener, it will be appreciated'tliattlie saidsharpener is simple and inexpensive in construction, and is-well adapted to withstand'thehardusage'to which devices of corresponding character are ordinarily subhave entered into a detailed descripti on oi the best embodiment ofmy invention of which l am cognizant, in ordervto impart a full, clear and exact understanding of the said embo'diment,b ut-it is obviousthat in the future practice of the inventionsuch changes or modifications may'bemade as 'fairly'fall within the scope ofmy invention as defined in the appended claims.
